WTBA World Tenpin Bowling Championships

The World Tenpin Bowling Championships is a global event that invites all countries that are members of the World Bowling to participate.

The event is held every two years and is split into 2 separate tournaments, one for men and one for women. These events are held alternately every year in different countries. Until 2005, the two events were always played at the same time, however, due to the growth of the championships in recent years it was decided to split the event up into separate men's and women's championships.

Players compete for medals in 6 different categories. Every bowler plays 24 games with 6 games in each category. The top 3 in each of the following categories are awarded medals:

After the conclusion of these events, the all-events medals are presented to the top 3 bowlers who have accumulated the most pinfall over the 24 games. This category is regarding as the most prestigious medal in world bowling.

The final medals are decided in the Masters category. The Masters event now comprises the top 24 bowlers from the all-events category. Top 24 bowlers bowl 6 games of qualifying with all-events pinfall carried over, with the top 8 after 30 games advancing to the next round. The next round of the masters is a round robin match play with 20 bonus pins for a win and 10 bonus pins for a tie. The top 4 with the highest pinfall total plus bonus pins advance to the semifinals. In the semifinals, the number one seed bowls the fourth seed and the second seed bowls the third seed. Semifinal matches are one game matches. The semifinal losers will share the bronze medal. The finals are a one-game match between the semifinal winners to determine the gold and silver medalists.

The format for the Championships has changed many times throughout its history. In the early years of the championships, men competed in 4 different categories, Doubles, 4-man team, 8-man team and masters. Up until 1963 women did not participate in the event. The first year that women did take part, they competed in 4 different categories, doubles, four-person team (European Style), four-person team (American Style) and masters. This is the only time the "European Style" has been used in the championships. In the following championships the European style four-person team was replaced with the five-person team event (American Style) and was used until 1979. Since 1979 both men and women have competed in the same categories that are used in the championships today. The masters event has only recently changed with the onset of the championships splitting into 2 different events. Up until 2005 the top 16 would bowl a 16-game Round Robin with the top 3 bowlers after the 16 games advancing through to a stepladder final. From 2005 to 2011, the masters was played using the matchplay style, best of 5 format. Beginning in 2013, the top 24 men and women in All-Events advanced to the Masters event. All players will bowl six games with the All-Events total carried forward. The top 8 after 30 games advance to seven games of round robin match play, where 20 bonus points are awarded for a won match and 10 bonus points for a tied match. The top 4 advance to the semifinals, which is a one-game match, 1 vs 4 and 2 vs 3. The semifinal losers will earn a bronze medal. The semifinal winners advance to a one-game final match to determine gold and silver medals.
